Atlantis has ENV vars that are bool: https://github.com/runatlantis/atlantis/blob/488a1ac92e80237c2ee3dc90de589f16eeba6765/runatlantis.io/docs/server-configuration.md?plain=1#L1082

but the larger problem is, when passing that via TF, it will render as bool, which is causing the json validation to fail since it declared all ENV vars are strings

and with TF, even something like this

content {
      name  = format("environment.%s", upper(set.key))
      value = format("%s", tostring(set.value))
    }

will still render as a bool if its

"true"
